  9. 5.4.3 Releasing a chassis requiring maintenance from the physical partition

5.4.3 Releasing a chassis requiring maintenance from the physical partition


5.4.3 Releasing a chassis requiring maintenance from the physical partition
This section describes the procedure for releasing a chassis requiring maintenance by using dynamic reconfiguration (PPAR DR) for the physical partition. The procedure described here is applicable only to a system with a building block configuration.
Note - For the versions of XCP and Oracle VM Server for SPARC/SRU that support dynamic reconfiguration (PPAR DR) of a physical partition, see the latest Product Notes.
Note - To use the dynamic reconfiguration (PPAR DR) function for physical partitions, you need configure the logical domains in advance according to "2.5  Dynamic Reconfiguration Conditions and Settings" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide.
  1. Confirm that the logical domains are not using the I/O devices in the chassis requiring maintenance.
    For details, see "5.3.1  Checking the operating condition of the physical partition or logical domain" to "5.4.1  Releasing the assignment of I/O devices."
  2. Log in to the XSCF shell.
  3. If the server requiring maintenance is operating as the master chassis, execute the switchscf command to switch the master XSCF to the standby XSCF.
    Enter "y" in response to the confirmation message.
    If the chassis requiring maintenance is the slave XSCF, go to step 5.
XSCF> switchscf -t Master
The XSCF unit switch between the Master and Standby states.
Continue? [y|n] :y
  1. Log in to the XSCF again.
  2. Execute the showboards command to check the status of the server connected to the chassis requiring maintenance.
    The BB-ID of the chassis requiring maintenance is indicated by the system board (PSB) number.
    In the following example, the [Fault] column displays "Degraded" for PSB 00-0, indicating that the system board is operating with some faulty parts.
XSCF> showboards -va
PSB  PPAR-ID(LSB) Assignment  Pwr  Conn Conf Test    Fault
---- ------------ ----------- ---- ---- ---- ------- --------

00-0 00(00)       Assigned    y    y    y    Passed  Degraded
01-0 00(01)       Assigned    y    y    y    Passed  Normal
02-0 00(02)       Assigned    y    y    y    Passed  Normal
03-0 00(03)       Assigned    y    y    y    Passed  Normal
  1. Execute the deleteboard command with the -c disconnect option specified to release the chassis requiring maintenance from the physical partition.
    If you have not manually released any of the following resources beforehand, be sure to specify the "-m unbind=resource" option: CPU core, memory, and PCIe root complex. With this option specified, the command automatically deletes the resource and then releases the system board.
Note - The -m unbind=resource option of the deleteboard command is supported by Oracle VM Server for SPARC 3.2 or later.
  1. In the following example, PSB 00-0 is released from the physical partition.
XSCF> deleteboard -c disconnect 00-0
  1. Execute the showresult command to check the end status of the deleteboard command that was just executed.
    The following example shows that "0" was returned as the end status since the execution of the deleteboard command completed successfully.
XSCF> showresult
0
  1. Execute the showboards command to confirm that the chassis requiring maintenance has been released from the physical partition.
    In the following example, the [Pwr], [Conn], and [Conf] columns all display "n" for PSB 00-0, indicating that PSB 00-0 has been released.
XSCF> showboards -a
PSB  PPAR-ID(LSB) Assignment  Pwr  Conn Conf Test    Fault
---- ------------ ----------- ---- ---- ---- ------- --------

00-0 00(00)       Assigned    n    n    n    Passed  Degraded
01-0 00(01)       Assigned    y    y    y    Passed  Normal
02-0 00(02)       Assigned    y    y    y    Passed  Normal
03-0 00(03)       Assigned    y    y    y    Passed  Normal
  1. Execute the ldm list-domain command from the control domain console of the physical partition to check for any change in the operating condition of the logical domains after the deletion of the system board.
